A condenser of the general character described above is disclosed in Van Deventer Patent 1,181,623 i ssued May 2, 1916.

- In condensers of this type after a certain ipredetermined-number of layers of insulat- 'ing-jsheets and conducting sheets-have been assembled so as to 've the desired capacity,

In order to insure that the clamps may not be pulled off the stack accidentally or otherwise, I have prov this trouble; hence, the principal object of invention is to provide means for.pre-

venting the terminal. clamps from being p said stack and in electrical connect on with ided means for preventing Figure 1 is a p lan view of a complete as sembled condenser, while {Figure 2 is a perspective view looking toi ward the side and end of the condenser.

integralwith the terminal clamps-1 and 2' being provided for mounting the condenser.

The terminal clamp 1 is provided with a pair of ears'6 and the terminal clamp 2 with a corresponding pair of ears 7. These ears are so constructed that their ends 8 are adapted to pass through perforations in two side members 9 and 10. These side members 9 and 10 are of strong insulating material and as the ends 8 of the ears 6 and 7 are bent over, as shown in Fig. 2, tension is applied to the terminal clamps 1 and 2 thereby holding them securely in position on the stack 3. As shown in the drawing, I prefer to mount the members 9 and 10 on opposite sides of the condenser stack in order to keep the thickness to a minimum, although, itis to be understood that an equivalent arrangement may be placed on the top and bottom of the stack engaging the lips 11 and 12 of the terminals 1 and 2, although, I have found it more convenient to place them on the sides of the stack as illustrated, particularly, where the lips 11 and 12 approach relatively near to eaeh'other as they may in some arrangements of a condenser.
